To get tickets for the 4:45 p.m. meet and greet at Nordstrom, fans had to purchase at least $75 of merchandise from Nordstrom’s Brass Plum department on Halloween. To get in line for cast member autographs at Hot Topic at 6 p.m., they had to have bought the store’s special edition “New Moon” T-shirt, also made available on Halloween. People camped out overnight for both.

Only the last event — a 7 p.m. Q&A session and musical performance from Anya Marina, whose work appears on the film’s soundtrack — will be free and open to the public.

“People are crazy for ‘Twilight,'” said Leah Bledsoe of Allied Integrated Marketing, which helped organize the event. “It’s the one thing you never have to worry about — people are going to show up.”

Film promotion is a group effort. With international box office a big target for the franchise, Stewart and Pattinson are doing events in Europe, having just appeared in France, Bledsoe said. Other cast members are doing their part in major cities around the world.

So who are Demetri and Felix? They’re members of the Volturi Guard, a 3,000-year-old “coven” of powerful vampires who enforce the laws of their world. Demetri is one of the better “trackers” among them. Felix, not as gifted as his fellow Volturi, has enormous strength.

Fewer than 100 people got tickets to the Nordstrom meet and greet, which is sold out. But wristbands are still available for the Hot Topic autograph signing — if you’ve got time between now and Thursday to buy a T-shirt at the Southcenter store. Five-hundred people are expected to line up.
